CPF extends 4% interest rate again, How long can it last?

Many people are not aware of the impact of such pegging. The average yield of the securities plus 1 per cent was merely 2.55% from Sept 1 last year to Aug 31 this year. CPF members were lucky because since 2008, CPF has provided a minimum 4 per cent interest, or floor rate and this minimum rate has been extended three times due to global economic conditions and exceptionally low interest rates.
